The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image.
Effective fixing and washing removes all unexposed silver salts and leaves only a small amount of residual fixer. Any significant quantity of fixer (thiosulphate) left in the print after washing will cause the image to deteriorate over time. Many other factors play a critical role in the long-term stability of gelatin silver prints.
Gelatin silver print of a presumed lost daguerreotype [5] The second earliest known photograph of Lincoln. From a photograph owned originally by George Schneider, former editor of the Illinois Staats-Zeitung, the most influential anti-slavery German newspaper of the West. Mr. Schneider first met Mr. Lincoln in 1853, in Springfield. "He was ...
The process rapidly spread and became a dominant method in Europe and America by 1894 since it had a visibly different color tone compared to albumen and gelatin silver prints. Late 1880s: Gelatin silver print This has been the major photograph printing process since the late 1880s up to the present. [3] Prints consist of paper coated with an ...
The emulsion contains light sensitive silver halide crystals suspended in gelatin. Black-and-white papers typically use relatively insensitive emulsions composed of agb silver bromide, silver chloride or a combination of both. The silver halide used affects the paper's sensitivity and the image tone of the resulting print. [2]
Currently, the standard analog photographic printing process for black-and-white photographs is the gelatin silver process. [1] Standard digital processes include the pigment print, and digital laser exposures on traditional color photographic paper. [citation needed] Alternative processes often overlap with historical, or non-silver processes.
A chromogenic print, also known as a C-print or C-type print, [1] a silver halide print, [2] or a dye coupler print, [3] is a photographic print made from a color negative, transparency or digital image, and developed using a chromogenic process. [4]
A single overall colour underlies the image and is most apparent in the highlights and mid-tones. From the 1870s albumen printing papers were available in pale pink or blue, and from the 1890s gelatine-silver printing-out papers in pale mauve or pink were available. There were other kinds of tinted papers as well.
